Are 5090s now utilized at full capacity? They used o render as fast as 3080tis
About a month ago (maybe a bit more), NVIDIA told Otoy they’re aware of an issue that’s been affecting some other render engines, where certain kernels take way longer than usual to initialize.
From the user’s side, it can look like Octane is taking forever to start rendering or that render times are unusually long. Right now, it doesn’t really seem like Octane itself is affected, but it could be.
The issue only affects the 50 series GPUs and should be fixed in the latest driver, though it might still show up in some cases. Might be worth trying drivers around 581.29, 580.97, or 577.00 to see if it makes any difference?
